The period echo function uses two parameters which can be constants or envelopes.
You can tell specify the period between echos and the volume factor between echos.
If you use a negative value as a period time, echo come before the original sound.
Also it is possible to specify the count of echo.
You can also get special effect when using short times.
You must specify the count of echos and the room in time where waves can put in.
This can made cyclic so you cannot hear the edge between the
end and begin when repeating the result. (like wallpaper)
You can let put the waves linear (every time a equal change) or use a Random
Time envelope. The outcome of random numbers are horizontal and the time is
generated via the envelope as a vertical value. With the envelope it is possible to have
most echos at the end for example.
Normally each echo has the same volume as the original sound, you can vary the volume
of each echo linear or with the Random Volume envelope. With a envelope you can make
many echo with a low volume and less with a high volume for example.
Each echo has normally the same speed. It is also possible the give each echo a own
speed with a Random Speed envelope just as the volume. Negative speed factors cause a reversed echo.
The same story counts for the balance with a Random Balance envelope. So you can make
real applause or you are between cows if you close your eyes.
Normally each part of the random echo (time, volume, speed and balance) has own dices.
You can let some parts share one dice (at all thinkable possible ways), for example you
can have:
- echo with a low volume have a high speed
- the strongest echos at the left side
- the fastest echos in the begin and the and and the slowest in the middle
(seen in time or balance or both)
- echo coming from left to right
- and more...
